Strong agree. I use a derivative that blocks snaps instead of direct Kubuntu now, and it wasn’t Just because of the snaps.

I use a derivative

Without Ubuntu Pro subscription the entire Universe repository does not receive any security updates by Canonical:

canonical.com/…/ubuntu-pro-enhanced-security-and-…

You should consider switching to an entirely independent distribution that does not lock security updates behind a paywall, perhaps something based directly on Debian or Fedora.

Update: Correction. While you do get five years of security updates for Universe on an Ubuntu LTS, those are updates done by the ubuntu community, not canonical. To get Universe security updates from Canonical, you do have to sign up to Ubuntu pro, which can be done without any payment, but as I describe in my original comment, does require creating an account.

While Canonical deserves the criticisms leveled by op (that I agree with), it’s also incorrect to say that they lock security updated behind a paywall.

Anyone that does use Ubuntu gets security updated until they stop supporting that particular release version, which iirc is for six years (I may be wrong, thus is from memory).

If you want extended security updates for a specific version of the os, you can elect to sign up to Ubuntu pro without paying any money. You do have to make an account, and if you so choose you can populate the account info with garbage info and a disposable email, and you’ll get extended security updates for that release version.
